The study aimed to examine the different contents of posts published in an online community for eating disorders among four groups (Pro-Ana, Anorexia, Bulimia, and Binge Eating Disorder). The hypothesis was that Pro-Ana group members would have a greater propensity to deny the negative aspects of their eating disorder and a greater social adherence to their own blog community compared to the other groups. 1791 posts, collected from December 2018 to March 2019, were analyzed using quantitative analyses of the text through T-LAB software (version T-Lab Plus 2020). The cluster analysis of the text showed that Pro-Ana group appears to be more represented by “social sharing” cluster compared to the other groups, exhibiting a greater tendency to exchange social support about their eating behaviors. Factorial space analysis reported that Pro-Ana people tend to be less capable to provide realistic representation of their eating disorder than the other groups. Finally, Pro-Ana group members showed a greater social adherence in terms of satisfaction ratings (ratio “likes”/“views” to each post) compared to the other groups.

该研究旨在检查在线社区中发布的关于四组（Pro-Ana、厌食症、贪食症和暴食症）饮食失调的帖子的不同内容。假设是，与其他组相比，Pro-Ana 组成员更倾向于否认他们饮食失调的负面影响，并且对他们自己的博客社区有更大的社会依从性。通过 T-LAB 软件（T-Lab Plus 2020 版）对文本进行定量分析，对 2018 年 12 月至 2019 年 3 月收集的 1791 个帖子进行了分析。文本的聚类分析表明，与其他组相比，Pro-Ana 组似乎更多地以“社交分享”聚类为代表，表现出更大的倾向来交换有关其饮食行为的社会支持。因子空间分析报告称，与其他群体相比，Pro-Ana 人往往无法真实地描述他们的饮食失调。最后，与其他组相比，Pro-Ana 组成员在满意度评分（每个帖子的“喜欢”/“观点”比率）方面表现出更高的社会依从性。
